  生产者行为 Producer behavior

  1. Producer surplus: market price – cost

  2. Revenue, cost and profit

  3. Production functions: short and long run短期和长期的生产函数

  Short run: only labor variable

  Long run: all variable

  4. Marginal product and diminishing returns边际产量和边际产量递减规律

  Marginal product (marginal return)

  The changein total product that results from a one-unit increase in the quantity of laboremployed.

  MP of A= additionaloutput/ additional input of A

  Marginalreturns start diminishing when MP decreases as L increases

  MP和MC的图!

  Increasing marginal returns

  When the marginal product of an additional worker exceedsthe marginal product of the previous worker

  Decreasing marginal returns

  When the marginal product of an additional worker is lessthan the marginal product of the previous worker

  5. Short-run costs短期成本曲线

  MC曲线最后是上扬的,是因为diminishingmarginal product,生产能力全部被利用之后,再增加边际投入,就会出现边际产量递减,边际成本递增。

  ATC=AFC+AVC

  TC=TFC+TVC

  6. Long-run costs and economies of scale长期成本曲线和规模经济

  economies of scale规模经济,指随着产量增加ATC不断下降,规模经济的产生是因为specialization&ability to purchase

  diseconomies of scale规模不经济,

  constant returns to scale规模收益不变指产量变动而ATC不变,或者说投入增加的倍数与产出增加的倍数相同。

  7. Cost minimizing input combination成本最小化的要素组合

  MPL/PL=MPK/PK

  8. Profit利润

  (1) Accountingprofit,economic profit

  会计利润(总收益-显性成本)和经济利润(总收益-显性成本-隐性成本)

  (2) Normalprofit

  指的经济利润为0(但依然赚着会计利润)
